Title: Double flex seal for tubular connection
Inventor: MALLIS DAVID LLEWELLYN
IPC: F16L15/00
Filed: 2001-08-10
Abstract: A threaded tubular connection has a box member including an internal thread, a pin member including an external thread engageable with the internal thread of the box member, and a protruding sealing surface disposed in the box member such that the pin member flexes radially inward upon passing the protruding sealing surface during make-up. The threaded tubular connection also has a recessed seal cavity disposed in the box member and a reverse angle shoulder at the pin nose that forces the pin member to flex radially outward into the recessed seal cavity of the box member upon final make-up. A method of forming a double flex seal for a tubular connection includes engaging an internal thread of a pin member with an external thread of a box member and flexing a pin nose of the pin member radially inward by passing the pin nose over a protruding sealing surface of the box member during make-up. The method also includes flexing the pin nose radially outward when a reverse angle shoulder of the pin nose comes into contact with a reverse angle shoulder of the box member during make-up and completing the double flex seal by finally making up the connection such that the pin nose of the pin member seats in a recessed seal cavity disposed in the box member.

Abstract: A process for converting composted organic material produced by optimized composting procedures into enhanced organic fertilizer for agronomic and oth er uses. The raw organic matter is processed into compost by optimized standard  methods. A wide variety of raw materials can be used in this invention. The finished compost isscreened to remove all particles approximately 1 cm in si ze or greater. This coarse material is recycled back into the composting proces s. In the first step of this invention, the material below 1 cm is further screened to separate out the compost fine particles of 1 mm or less. A major  proportion of the particles should be below 150 microns. The particles betwe en 1 mm and 1 cm are rejected, and may be used for other purposes. In the next step, the compost fine material is mixed with suitable forms of plant nutrients, i.e. ammonium nitrate, to bring the plant available nutrients to a fertilizer grade level in the pellet. In the final step the compost fine material is pelleted at a pressure between 2,000 and 6,000 psi to form a fertilizer pellet of an appropriate density so that the nutrients will be released into a soil medium, or plant growth substrate, at a rate required f or optimum plant growth. The compression process binds the chemical fertilizer into the pellet andassists in the timed release of the nutrients from the enhanced organic fertilizer pellet. The enhanced organic fertilizer pellets can be applied to farm fields, gardens, and the like, in the normal way.</SD OAB>
